Communication system, electronic control unit, wake-up retention program stored on non-transitory storage medium, and wake-up retention method

An electronic control unit in a communication system mounted on a movable object, wherein the communication system includes a plurality of electronic control units and a management device arranged to be communicable therebetween, and the electronic control unit is included in the plurality of electronic control units,

• the electronic control unit being configured such that:
• the electronic control unit is activated by supply of power from an outside thereof, and stopped by cutoff of the power from the outside;
• the electronic control unit in a state of being supplied with the power is activated by switching over to a wake-up state and is stopped by switching over to a sleep state based on a communication frame received from the outside thereof via a communication line;
• and
• the electronic control unit executes a retention operation to retain the wake-up state, wherein input of predetermined control information triggers execution of the retention operation,
• wherein the plurality of electronic control units and the management device are each provided by at least a processor and a memory.
